First off, bought the truck on GM's reputation. Decent design, good comfort, but performance, and gas mileage is something to be desired. I had a '96 Nissan 4 banger that would run circles around this GMC. Come on guy's get with it.
Comfort, and audio system.
More power, and better gas mileage. Try to get a little more room behind the seat.
Since I have had my Sonoma, I have gotten avg. of 26mpg. The power of the 4 cyl engine leaves to be desired, however, it is a good crusing truck and rides very nice. It is sporty looking and really fun to drive.
